How Geothermal Works

As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from sweltering summers to freezing winters; Greensburg included. Did you know there is a fairly constant temperature, regardless of climate or season, just below the ground?

The Earth's crust absorbs 47% of the sun's heat (energy) and is maintained in the ground a few feet beneath the surface. WaterFurnace geothermal systems draw from this free heat with an earth loop. This innovative technology recovers the sun's heat supplying your home or office with central heating and cooling.

Geothermal Heating

Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and delivers this warmed air through a standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available.

Geothermal Cooling

The heating process is reversed in the cooling mode - creating cool, conditioned air all through the home. Instead of extracting heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
